<hr>
<p>
<b>fgets</b> is used to read a line of data from an external source.<p>
<hr>

<pre>
Library:   stdio.h

Prototype: char *fgets(char *s, int n, FILE *stream);

Syntax:    char  Data[80];
	   char *ReturnCode;
	   FILE *FilePointer;

	   ReturnCode=fgets(Data, 80, FilePointer);

	   ReturnCode == NULL when an error occours. The EOF is 
	   considered to be an ERROR!
</pre>

<h2>Notes</h2>
<ul>
<li>fgets should be used in preference to <a href=gets.html>gets</a>
as it checks that the incoming data does not exceed the buffer size.
<p>

<li>If fgets is reading STDIN, the 
<a href=escape.html>NEWLINE</a> character is placed into
the buffer. <a href=gets.html>gets</a> removes the NEWLINE.
</ul>
